Hend seized a one-shot lead over South African Darren Fichardt, who carded a matching 63 in the second round, with a two-day total of 13-under-par 127.
The three are among 12 players with holes to complete and round three will resume at 07:00 BST on Sunday, with round four scheduled to start at 08:55 in a three-ball format.
Scott Hend and wife Leanne ponder a shot during a rain-soaked round three in Switzerland. On Saturday, play was suspended because of fog, while fading light brought the leading groups in early. It's never nice to see, but we kept our nerve and just played really smart all week.
Thai star Thongchai Jaidee, Fabrizio Zanotti of Paraguay and Asian Tour rookie Todd Sinnott of Australia stayed four shots off the pace in third place following respective rounds of 66, 65 and 66.
The Sheffield-born player briefly held a two-shot lead before making a bogey on the 17th hole.
Hend showed his delight in holing a two-metre birdie putt at the par three, 13 hole by throwing both arms into air and move back to 11-under par on the Crans-sur-Sierre high in the Swiss Alps.
It's weird to say for a 23-year-old, but Matt Fitzpatrick is in the winner's circle again after a solid absence.
The margin doubled by round's end as Fitzpatrick made a late bogey and Hend produced 1-under golf to finish his round via an eagle-bogey stretch.
A long day for Fitzpatrick began with an 8 a.m. tee time for the final three holes of his third round.
Defending champion Noren did complete his round and is within six shots of Hend after a two-under 68.
The lead was gone minutes later when Fitzpatrick bogeyed the par-4 17th, after finding a green-side bunker with his approach, and Hend birdied the par-5 15th.
Lee Westwood, the 1999 victor at the Crans-sur-Sierre club that is blanketed with snow each winter, finished on level par after a closing 69.
